this is kind of a rough guide, just ignore the parts about prepping the quest alt or whatever, unless you use one of course. Fsm comes in handy too.
I changed my alt on my 89 coupe a few weeks ago. Ka24de alts will work with single cams(i used one from a 97 on mine), the terminal and grounding points are different, but that doesn't really matter. Its pretty straightforward its just in a b**** location and might have to get under the car some. Good luck!
